Possible Causes

Weak grill or convection heater, Failing cavity temperature sensor, Poor door seal causing heat loss, Faulty heater control on PCB

How to Fix / Troubleshooting

SAFETY: Unplug the microwave and allow it to cool before inspection.

E20 indicates the cavity is not heating as expected in grill/convection mode.

  • Step 1 – Door seal check:
    • Inspect the door gasket for gaps, burns, or deformation.
    • Ensure the door closes firmly without play.
  • Step 2 – Heater function:
    • Start a grill or convection cycle and carefully feel for heat at the top or rear (do not touch elements directly).
    • If little or no heat is produced, the heater may be weak or open.
  • Step 3 – Internal inspection (for DIYers):
    • Remove the cabinet and check heater wiring and connectors.

Heater or sensor replacement should follow SilverCrest specifications and may require a technician.
